MEASURE-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 540,130, dated May 28, 1895.

Application filed April 19, 1894.

To aZZ whom it may concern:

Be it known that 1, JOHN H. G. ZUNNER, a citizen of the United States, and a resident of Boston, in the county of Sufiolk and State of Massachusetts, have invented new and useful Improvements in Measure-Indicators for Pitching Apparatus, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in measure indicators for pitching apparatus for pitching barrels and although especially designed for such purpose it may to advantage be used for the purpose of measuring the flow of liquids in a general way without departing from the essence of my invention. 7

In pitching apparatus for the purpose of coating the interior of lager beer or ale barrels with molten pitch or rosin, it is desirable to employ means for regulating the quantity of liquid pitch that is to be drawn from the pitching apparatus to the barrel according to the size of the latter and for this purpose I use in connection with the stop cook or valve on the discharge pipe leading from the kettle of the pitching apparatus, a measuring device actuated by said stop cock so as to indicate to the man in charge that the proper quantity of the pitch or rosin has been discharged into the barrel to be pitched.

In the drawings I have represented, in Figure 1, a longitudinal section of a pitching apparatus, partly shown in elevation and having its stop-cock connected to a hydraulic measuringdeviceorquantity-indicator. Fig. 2 represents a front elevation of Fig. 1..

A, represents the furnace or fire pot of a pitching apparatus having the ash pit B below it as usual.

O is the kettle containing the pitch or rosin D to be heated which kettle is preferably arranged above the furnace A with an annular heating space E left between said kettle and the inclosing shell F as usual.

G is a discharge pipe leading from thelower part of the kettle O and provided with a suitable cock, valve, or cut ofi H provided with a handle hfor the operator to take hold of in opening and closing said valve or out 01?.

I represents the barrel that is to be pitched and coated on its inside with the molten pitch Serial No. 508,101. (No model.)

or rosin from the kettle O as .is common in pitching apparatus of this kind.

h is the upwardly projectingspiudle of the valve or cut off H and I have shown its upper end journaled in abearing bracket K prefer ably secured to the shell F and provided with a bevel gear H having its teeth meshing in the teeth of a bevel pinion Z secured to a shaft L suitably journaled in hearings in the bracket K.

To the outer end of the shaft L is secured a transparent glass tube M containing liquid m and having a contracted or reduced mid way orifice m as shown in Fig. 1. The ends of the tube M are graduated so as to correspond in gallons or otherwise with the flow of the liquid pitch from the discharge pipe G when the cook or valve is open. Normally the liquid m in the glass tube M is contained in the lower portion thereof.

By opening the cock H the tube M is turned half a revolution causing that portion thereof which contains the liquid to be held uppermost and causing the liquid therein to pass slowly through the orifice m into the now lower compartment of said tube which is indexed or graduated to correspond in gallons, &c., with the amount of'pitch passing out through the cock H and its discharge pipe G. If for instance it is desired to discharge one gallon of pitch into the barrel, all that the operator has to do is to look on the tube M and when he finds that the liquid in the lower portion of said tube M reaches the mark 1 thereon he knows that a gallon has been discharged into the barrel and consequently closes the cock H by which the measuring tube M is reversed and the liquid contained therein caused to run into its lower compartment where it remains until its position is reversed by the next opening of the cock or valve H and so on, thus indicating to the operator the amount of pitch that has been discharged from the kettle G into thebarrel I.

d\have shown the measuring device as electrically operated by the opening of thevalve or stop cockII and I have for thispurpose shown an electrode h on thehandle h adapted to be brought in metallic connection with a stationary electrode 9 on the pipe Gwhi'ch electrodes are connected respectively by means o f wires h and g to the ele'ctro magnet Qa's shown. H is a battery or current nerator 1b ated in the circuit as shown/P is the registe \or indicator having a graduated scale 5 P and movable index pointer pisecured to the spindle p as shown.

I have shown a rocking armature lever Q pivoted at q and having/armature q adapted to be attracted to the electro-magnet 0 when the circuit'is closed and provided with a suitable springp by which said armature lever is caused to-"vibrate as long as the circuit is closed by'which its pawl shaped end Q is caused to engagewith a ratchet wheel P" on the index pointershaft so as to cause the index pointer to move-in front of the dial P and thus indicate the amount of liquid passing through the valve or cutoff H as long as the latter is kept open.

I wish to state that I do not desire to confing mysclf to the exact electrical connections a mechanism as shown as any other suitle mechanism may be used Withoutchang- Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim 1. In a measure indicator for pitching apparatus, the combination with a discharge 3o faucet directly connected to the liquid containing vessel, of a quantity indicating device comprising an oscillatory, transparent tube having a contracted central portion forming a passage communicating with its opposite ends and bearing a fixed, determined relation to the area of the discharge faucet, said tube being partially filled with a liquid and provided with a graduated scale, and means operated by the faucet for oscillating said tube, substantially as described.

2. In a measure indicator for pitching apparatus, the combination with a discharge faucet directly connected to the liquid containing vessel, a vertical spindle connected to the turning plug of the faucet, a bevel-gear mounted upon the end of said spindle, a bevelpinion meshing with said bevel-gear, and an oscillatory trans-parent tube mounted on a horizontal shaft turning with said bevel-pinion and having a contracted central portion forming a passage between the opposite ends of the tube bearing a fixed, determined relation to the area of the discharge faucet, said tube being partially filled with a liquid and provided with a graduated scale, substantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 12th day of April, A. 'D. 1894:.

JOHN H. G. ZUNNER.

Correction in Letters Patent No. 540,130.

It is hereby certified that in Letters Patent N 0. 540,130, granted May 28, 1895, upon the application of John H. G. Zunner, of Boston, Massachusetts, for an improvement in Measure Indicators, an error appears in the printed specification requiring correction as follows, to Wit: All matter between line 96, page 1, and line 24, page 2, both inclusive, should be stricken out, the same having been erroneously printed as a part tion therein that the same may conform to the record of the case in the Patent Oflice.

Signed, countersigned, and sealed this 2d day of July, A. D. 1895.
